Thread: Uber light Suppressors

Any one had any experience with the Roedale Delta IV or A-tec CMM-4 suppressors, they look superb for ultra weight savings.

Yes, Roedale, as good as any NZ can I've shot it next to for suppression, better than some, half the size, very light, replaceable baffles means maintenance is easy.

Well engineered then.

Is there a case capacity limit? i.e. suitable for 60 grains or less?

Yes, you can add baffles for larger cases though. Which obviously increases the weight.

Adding baffles wont decrease pressure in the first chamber(if your worried about blowing it up) tho just make it quieter. The only way to decrease pressure in the first chamber(for short barreled magnums ect) would be to increase that chamber volume or limit the gas entering that chamber.

In theory no chambering should be more than 65 000 PSI right? Magnum or not. 270 is run at this now days...
Roedale has a very informative website too...
Roedale
Main page

You can see they have a R&D section there as well as FAQ's.

Gimp's wee Delta 4 is better at suppressing noise than my standard Gunworks for less than half the size and weight. I am shooting 46gr of 2209 through my 6.5, whereas he is shooting 42gr through his 6.5...

WTF is Uber? im guessing its a German word.
It gets thrown around a lot these days.What does it mean exactly?

A lot of light Ie Uber light. Would be an oxymoron then right? ie the silent thunder, the defening silence etc etc

Tussock Gave me a straight answer

I was talking more about making it quieter with the bigger cases. Changing the first 1-2 baffles to steel is probably a good idea with a magnum calibre?? I would have to check with the manufacturer. I don't own anything using more than 42gr of powder at the moment

The problem with suppressors and pressure as I understand it is the shorter the barrel the more pressure at the muzzle
Having a chamber pressure of 65,000 doesn't mean that will be the pressure at the muzzle and they are all the same. It's quite far from it.
So a suppressor on a very short barrel is subjected to more pressure the the same load on a longer barrel

JUst shot a new local one at 356 grams on a 6,5.
I dont know if they have been released until the sika show so wont name it yet
it was as quiet as his old model and as quiet as the south island one
good to see the locals still developing their wares

Dude my standard Gunworks one is 380grams on the scales. Roedale is getting close to half the weight of that and half the length.

What is this "spigoted muzzle" ?





Spare Parts:
Spigoted Expansion Chamber
We also have a Spigoted model that allows owners of rifles already machined with the spigoted type thread, that in use with some of the BR Tuote Reflex T8 Moderators
to convert to the Roedale Delta Moderator without having to have thier rifles re threaded and without having to make do with an unsightly gap between the Moderator
and the step of the spigot to the main barrel diameter.
Spigoted moderators or rear ends are avaialble in the following thread sizes:
M14x1 Spigoted
M17x1 Spigoted

Roedale Precision - Sound Supressors / Moderators

Would this go some way to reinforcing the end of your barrel and reducing leverage ?
